Repair kit for preparing polymeric compositions for repairing surfaces and methods of use thereof

Abstract

A repair kit for use in preparing a polymeric composite material and methods for preparing the polymer composite material are described. The repair kit includes a sealed container and a first removable divider arranged transversely across the sealed container. The divider is configured to engage the sealed container to form a first compartment and a second compartment. The first compartment and the second compartment are isolated from one another when the first removable divider is engaged with the sealed container. The first compartment contains a resin component and the second compartment contains a reactive component. The sealed container is configured such that removal of the first removable divider enables mixing of the resin component and the reactive component within the sealed container. The repair kit may also include a second removable divider to form a third compartment. The repair kit may also include a catalyst and a filler. The polymeric composite material can be used in repairing damaged surfaces, including pavements, roadways, facilities, structures, and railway infrastructure.

Description

FIELD OF THE INVENTION[0001]The present disclosure is generally related to a repair kit and a sealed container comprising components that can be mixed to form a polymeric composition for use in repairing damaged surfaces and methods for preparing such composition for use in repairing the damaged surfaces. Exemplary surfaces include pavements, roadways, facilities, structures (e.g., bridges), and railway infrastructure.BACKGROUND OF THE INVENTION[0002]Polymeric composite materials can be used to repair and restore damaged surfaces such as cracked pavement. For example, road repair crews can use polymeric composite materials to patch cracks, holes, and the like along a stretch of roadway. Polymeric composite materials generally include a mixture of a resin component, a reactive component, and a filler component. The components can be mixed together to form a polymeric composite that can be used in repairing damaged surfaces. Once the components are mixed together, the polymeric compos...

AI Technical Summary

Benefits of technology

The invention is a repair kit for a sealed container that allows the combined contents of different components to be mixed without compromising their individual properties. The kit includes two removable dividers that create separate compartments within the container, with each compartment containing a different component. The components can be mixed when the dividers are disengaged, providing flexibility in the composition of the repair material.

Problems solved by technology

Unfortunately, conventional methods of producing polymeric composite materials onsite require the use of mixing equipment, which can be cumbersome, requires electrical power, and can result in user exposure to undesirable chemicals during mixing.

The batch mixing uses bulky and expensive equipment and instrumentation to mix the components.

It can be difficult to transport the bulky equipment to more remote locations for surface repairs.

Additionally, because of the size of the batch mixing equipment, it can be difficult to have the equipment immediately at the site of repair, thus the polymeric composite materials typically have to be relocated quickly to the site of repair to avoid the polymeric composite material curing and hardening before the repair can be made.

Polymeric composite materials comprising sand as filler may experience a phenomenon commonly referred to in the industry as “crashing out,” wherein the sand that has been mixed together with and suspended in the polymeric composite material falls out of suspension and settles to the bottom of the container holding the polymeric composite material thus making the material unsuitable for use.
